Title: Transfer paper and dry-strip transfers made with such paper
Inventor: EDGE NORMAN
IPC: B44C1/17
Filed: 1952-11-20
Abstract: 728,089. Transfers; compound sheet materials. BRITTAINS, Ltd. Sept. 8, 1953 [Nov. 20, 1952], No. 29400/52. Class 140. [Also in Group XVI] Transfer papers according to Specification 727,825, and particularly those containing a polyethylene or polychlorotrifluoroethylene as the translucent film material, are modified by omission of the tissue paper, the bond between the translucent film and the backing paper being such that the latter is dry-strippable without damage to either surface. The film is preferably controlled to a thickness of 1 mil. during application by extrusion-lamination to glassine or other smooth impervious backing paper, e.g. of 4 mils. thickness. The polyethylene may contain an anti-oxidant, or may be modified by waxes or polyisobutylene or both. A transfer film may be formed on the polyethylene surface by brushing on a solution of (a) low viscosity cellulose acetate plasticized with 50 per cent by weight of diethyl phthalate in an acetonemethyl glycol mixture; or (b) polyvinyl alcohol in a water-ethyl alcohol mixture, preceded or not by a nitro-cellulose lacquer plasticized with 57 per cent of trixylenyl phosphate; alternatively a lithographic print of linseed oil litho varnish and pigment may be applied. The free surface of the transfer film may be overprinted with a solvent- or heat-activatable adhesive, to obviate siezing of the receiving surface.

Title: Barium ceramic material and the method of making the same
IPC: C03C10/16
Filed: 1960-08-30
Abstract: A strong electrically insulating ceramic material is formed of a homogeneous microcrystalline mass composed predominantly of synthetic barium-containing crystals and has the following composition by weight:- <TABS:0955818/C1/1>  The ceramic material is made by first forming a melt of the above composition, such as by mixing a batch of the following materials: MgO, BaCO3, MgF2, Li2CO3, kaolin and flint the kaolin supplying some of the SiO2. The melt is cast at about 1375 DEG  C. into a mould, with or without being subjected to a pressing operation, and allowed to cool to below its softening-temperature, e.g. 700 DEG  C., to arrest crystal formation, forming a vitreous material. The cast material is then removed from the mould and placed in an annealing furnace at 700 DEG  C. and heated first up to 800-900 DEG  C., and then to 1050 DEG  C., prior to gradual cooling to room-temperature, to allow the material to convert to a microcrystalline ceramic by autocrystallization.

Title: Improvements in or relating to alternating current generators
IPC: H02K19/30
Filed: 1952-11-25
Abstract: 723,725. Dynamo-electric machines. RONA, E. Nov. 25, 1952 [Nov. 26, 1951], No. 29862/52. Class 35. An alternator exciter is arranged for compounding by providing its armature with an additional winding carrying the A.C. load current and having some of its poles unwound, the wound ones being saturated. In the form shown, the alternator armature 4 has the same number of poles, viz. four, as the exciter and both armatures are mounted on the same shaft. The exciter armature 5 carries a commutated winding w<SP>2</SP> and a three-phase additional winding w<SP>3</SP>, of which only one phase is shown, carrying the load current from the alternator armature. The exciting winding w<SP>1</SP> of the exciter poles p<SP>1</SP>, p<SP>2</SP> and the field winding w<SP>4</SP> of the alternator are energized from brushes b<SP>1</SP>, b<SP>2</SP> which are excited by the saturated poles p<SP>1</SP>, p<SP>2</SP>. In order to effect compounding, an additional field winding w<SP>5</SP> on the alternator is energized from the remaining brushes b<SP>3</SP>, b<SP>4</SP> there being no voltage between these brushes at no load. When load current passes through winding v<SP>3</SP>, the poles p<SP>1</SP> and p<SP>2</SP> are little affected because of their saturated condition, but a potential appears between brushes b<SP>3</SP> and b<SP>4</SP> depending on the magnitude and phase of the load current, so that the alternator field is strengthened for lagging and weakened for leading loads. In a modification, not shown, the exciter poles p<SP>1</SP>, p<SP>2</SP> carry additional windings energized from opposite brushes b<SP>1</SP>, b<SP>3</SP> or b<SP>2</SP>, b<SP>4</SP> or else b<SP>3</SP>, b<SP>4</SP>, to compensate these poles against armature reaction. It is stated that only a single pole need be excited and a rod is shown in which the exciter poles are of uneven size and distribution.

Title: Improvements in tacheometric telescopes and like optical instruments
IPC: G01P3/36
Filed: 1924-12-15
Abstract: 242,468. Wilson, J. S., and Taylor, E. W. Dec. 15, 1924. Telescope systems. - Tacheometric telescopes and like instruments of the type focussed 'uy the movement of an internal negative lens, comprise an objective and focussing lens of equal and opposite power. The separation between the relatively fixed objective and the system of marks in the fixed eyepiece is about 1.11 to 1.12 times the focal length of the objective or the focusing lens, the vertical axis of the telescope being situated half-way between the objective and the system of marks. By this construction the difference between the angles subtended by the object at the principal point of the objective and by the image of the stadia intercept at the principal point of the focusing lens is never greater than one thousandth of the angle subtended by the object at the anallatic point A for any object between 600ft and 20ft distant, so that the determination of the distance by the image of the stadia intercept will not differ appreciably from the correct distance. Specification 215,673 is referred to.

Abstract: 406,084. Filling-machines. SIMON, Ltd., H., and BRIAN, J. C., Bird Hall Lane, Cheadle Heath, near Stockport. Oct. 27, 1932, No. 30115. [Class 94 (i).] A jigging apparatus for sacks comprises a plate a to receive the sack r<1>, pivoted at t to brackets on a spindle b. An arm d is secured to the spindle by trunnions on a boss d<1> and carries a roller e engaging a cam f rotated by a belt pulley h to impart an oscillatory movement to the plate a. The arm d is pivoted to the boss d<1> to allow lateral movement of the roller e to a position out of engagement with the cam f. When there is less than a predetermined weight on the plate a, the weight of the arm d is sufficient to tilt the roller e out of contact with the cam f, and the plate a is thus moved into an inoperative position. The disengagement may be effected by a hand lever k connected by links m, n to a bell-crank lever which moves a slide h through guides i. The slide carries projecting pieces o, one on each side of the lever d and moves the latter accordingly. The bell-crank lever may also be operated by a link p, Fig. 3, connected to the control mechanism of a weighing machine. The control comprises a handle q connected to levers r which is actuated so that the roller e is disengaged to stop the jigging operation while the weighing takes place.

Title: Dampers and damped springs
Inventor: KENDALL GILES ARTHUR
IPC: F16F9/30
Filed: 1962-08-07
Abstract: 971,965. Rubber springs and dampers. MENASCO MANUFACTURING CO. Aug. 7, 1962, No. 30241/62. Heading F2S. A damper or damped spring, Fig. 6, comprises a piston-rod 15 which has a piston head 16 and is enclosed within a rigid chamber 14 filled with a compressible solid 17a, e.g. of silicone rubber, for producing a damping force on the rod 15 and piston 16 as the rod moves into the cylinder, and means, e.g. a gland 22, for varying the pressure of the solid material so that the type of damping acting upon the rod and piston can be selected. The gland 22, which is screwed into an end 14c of the casing 14 around a piston-rod part 15a, has sealing rings 26, 27 and an extension 28 with an angled buffer surface 29 opposite 'a corresponding buffer surface 30 on the casing 14. The pistonrod part 15b extends through a seal 21 into a compartment 19 in an extension 14b of the casing 14. Instead of, or in addition to, the gland 22 compressible solid may be introduced into the casing through a pipe leading to a reservoir containing compressible solid and provided with pressure adjusting means. According to the pre-set pressure of the material 13 either friction or viscous, i.e. shear, damping is produced on the shaft rod 15a, 15b and on the surfaces 16a, 16b, the inclination of which also has an influence upon the kind of damping produced. Damping also results from plastic flow of solid material 13 through the annular space between the piston 11 and the casing 14 and also from the development of different pressures 'at opposite sides of the piston. In alternative constructions in which the damper also functions as a spring the piston-rod parts are of differing size or the piston-rod extends through one end only of the casing.
